About the Airtac ACED Double-acting Compact Cylinder ACED125X200B
A double acting compact cylinder built to ISO 21287, the ACED125X200B pushes a 125 mm bore through a 200 mm stroke with a 25 mm rod exiting BOTH covers. Because both strokes work on the rod-side area, output is identical in each direction: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa. The B code gives a male rod thread, and the 1/4" PT port matches the bore. The hard-anodized aluminium body carries magnet slots along its length, and the S45C hard-chrome-plated rod shrugs off wear in daily production duty.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this heavy thrust class still fits presses, gantries and guarding where a full-length body cannot. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the through-rod resists rotation and side load while giving a symmetric mount. Practical sizing: plan on roughly 3534 N of real work at 0.5 MPa, which is about 360 kgf, so halved for a 2:1 margin this cylinder lifts about 180 kg vertically. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø125mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 5890 N |
| 0.7 MPa | 8247 N |
| Max (@1.0 MPa) | 1201 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACED Double-acting Compact Cylinder ACED125X200B Is Used
Heavy press and forming fixture
The 5890.5 N double-direction thrust at 0.5 MPa clinches, stamps or presses steel brackets in a compact fixture head, where the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
Vertical lift on a packaging gantry
With about 180 kg of vertical lift capacity at a 2:1 margin, the through-rod carries the tooling on both faces and the fixed TPU bumpers absorb the descent at each end of the 200 mm stroke.
Clamping station on an automotive machining line
The symmetric double rod clamps a cast housing from both sides with equal 8246.7 N force at 0.7 MPa, and the male rod thread (B code) accepts an I or Y knuckle for the linkage.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X200B the Right Cylinder?
At 5890.5 N per direction at 0.5 MPa, this is near the top of the ACED range; step down to the ACED100X200B (3769.9 N) if the load is lighter, or up is not possible in this series since 125 mm is the largest bore. Stroke 200 mm sits inside the 300 mm maximum standard stroke for bore 125, so no made-to-order length is needed. Remember the piston drifts if air is lost - for a held load add a rod lock or pilot check valve. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face. This unit has no magnet; order the -S code instead if CMSE / DMSE switches are planned.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACED Double-acting Compact Cylinder ACED125X200B FAQ
Yes - a rod exits both covers, so both strokes use the rod-side area and force is equal either way: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, with a maximum of 1201.3 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 1/4" PT port matches the 125 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body and S45C hard-chrome rod. A fixed TPU bumper at each end absorbs end-of-stroke energy but never locks or holds a load - use a rod lock or pilot check for that. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard face. Sensors need the optional -S magnet code; this model (no S) has no magnet, so CMSE / DMSE switches cannot be mounted on it.
